Expo AI Runtime

One TypeScript API (ExpoAI) over the best AI a phone can offer: Apple Foundation Models (on-device, iOS 26+), Android Gemini Nano (on-device, via ML Kit GenAI / AICore), and an explicit, app-controlled cloud fallback — with runtime capability detection, normalized errors, and privacy metadata on every result.

The core is provider-agnostic. Provider packages register themselves at import time, and the router picks the best available provider for each request. Your job in a consumer app is to wire the packages, detect what the device can do, call the right method, and respect the privacy rules.
